Peter Burling and Blair Tuke have stamped a mark of dominance over their rivals on day three of the 49er world championships in Clearwater Florida, where the Olympic men's skiff, women's skiff and mixed multihull are vying for their 2016 world titles.

The 2012 Olympic silver medallist and defending world champions won all four of their heats on day three of the six day regatta and now show a clean-streak of five race wins as the regatta moves into gold fleet racing.

With net four points Burling and Tuke have the lead from Australian pair Nathan Outteridge and Ian Jensen who also sailed well today to lie six points adrift of their Kiwi rivals.
